The Bordeaux tramway network (French: Tramway de Bordeaux) consists of three lines serving the city of Bordeaux in Aquitaine in southwestern France.

The first line of Bordeaux's modern tramway opened on 21 December 2003; further extensions have increased the route length to 43.9 kilometres (27.3 mi).[1] The system is notable for using a ground-level power supply of the Alimentation par Sol (APS) system in the city centre. It is operated by Keolis Bordeaux since 1 May 2009.

The first tramway line of Bordeaux, with cars towed by horses, dates back to 1880. In 1946, the public transportation system in Bordeaux had 38 tram lines with a total length of 200 kilometres (120 mi), carrying 160,000 passengers per day. A rudimentary system of ground-level power supply was used on some stretches with mixed success. As in other French cities at the time the mayor, Jacques Chaban-Delmas (first elected in 1947), embraced anti-tram arguments and decided to terminate the operation of the tramway. He found the tramway to be old-fashioned compared to the bus and its attachment to set tracks on the ground hindered the increasing flow of cars. The lines were closed one after the other. In 1958 the last line of tramway was terminated.

By the 1970s the failure of the "all car" transport policy had become obvious, but Chaban was not prepared to backtrack. A grandiose automatic light underground railway (VAL) scheme was promoted; it even received the backing of a majority of the city's councillors, but fell victim in the end not just to the fierce opposition of the local transport users' association TRANSCUB but to the hard reality of the fine sandy nature of the city's soil. The VAL idea was dropped. Chaban remained.

Bordeaux had to wait until 1995 and the election of Alain Juppé as mayor – as well as the total strangulation of the city by its transport problems – before the situation was tackled. Following two years of studies, the Bordeaux Urban Community adopted the tramway plan in 1997. Recognized by the central government in 2000 as a Public Interest Project, the scheme got under way and by 21 December 2003 was carrying passengers on three routes, one of which was extended on 25 September 2005, with further extensions opened in 2007 and 2008.

A particular feature of the new Bordeaux tram network is its ground-level power supply system which is used in the city centre to avoid overhead wires spoiling the view of buildings. This was the source of many difficulties and breakdowns when first introduced. Improvements since then, however, have increased reliability and the network is now one of Bordeaux's principal plus points, valued not just for enabling the people of the city to get about easily but also for its contribution to the aesthetics of the city and its quality of life. The new trams are an essential part of Bordeaux's current tourist redynamization strategy. The three lines were extended in 2007 and 2008 to reach several housing estates as well as the suburb of Mérignac. The whole system is under video surveillance, with a camera installed inside each vehicle.

Trams operate on all lines from around 4.30am until midnight, seven days a week with later service on Thursdays, Fridays and Saturdays until around 1.30am. All stops have panels showing the waiting time until the next tram. On Sunday and holiday mornings, trams run every 30/40 minutes until around 1000am then every 20 minutes. Weekday and Saturday services operate every 10 – 12 minutes with additional service during 'rush hour' and for special events. However there is no service at all on May 1, Labour Day holiday.

The first line (Line A) was opened on 21 December 2003 in the presence of PresidentJacques Chirac, and the mayor of Bordeaux, Alain Juppé. It ran between Mériadeck and Lormont/Cenon. It was extended on 26 September 2005 to new termini at the Pellegrin Hospital and Saint-Augustin. Further extensions opened in 2007; from Cenon to Floriac on 27 February 2007; and from Saint-Augustin to Mérignac Centre on 21 June 2007. A new extension from Lormont Lauriers to Carbon Blanc opened in May 2008.

Line C was the next to open between Quinconces and Gare St Jean, on 24 April 2004, following delays. The final northern section to Les Aubiers was opened in February 2008, as was the southern extension from Gare St. Jean to Terres Neuves.

Line B was partially opened on 15 May 2004 and throughout on 3 July 2004. 29 May 2007 saw the opening of the first phase of its 2007 extension of when it began to serve Pessac Centre at its western end. On 23 July 2007 a further extension of the line from its previous terminus at Quinconces, along the left bank of the Garonne, to a station at Bassins à Flot opened. The final extension to northern terminus of the line at Cité Claveau, near to the Pont d'Aquitaine on the Bordeaux ring road, opened in October 2008.

The main depot for trams is at Thiers Benauge (off Line A) and a secondary depot has opened on Line B at Rue Achard on the new extension towards Claveau.

All trams are air conditioned and have a low floor. The rails are standard gauge (1,435 mm (4 ft 81⁄2 in)) and power is 750V DC. The maximum speed is 60 km/h with an acceleration of 1.15 m/s². The deceleration obtained from emergency braking is 2.85 m/s².

Line B has a new branch under construction at its southern end. This will run from Pessac Bougnard to Pessac Alouette via a major hospital. Due to be in service summer 2015. The existing line B continues from Pessac Bougnard to Pessac Centre.

Line C is being extended at its southern end from Terres Neuves Bègles southwards towards Villenave-d'Ornon, expected to be in service April 2015. Line C is also being extended at its northern end, from Les Aubiers to a new terminus at the Parc Des Expositions in the Bordeaux Lac commercial and exhibition district. The first new section, a short distance to a station called Ginko, opened in February 2014. The remaining 3 kilometres will follow early in 2015.

A 'tram-train' project is also under way.[5] This 7.2 kilometres (4.5 mi) line[5] will be a branch from existing Line C, turning off between Place Ravezies and Les Aubiers. It will join the route of the former Médoc line at La Vache then run parallel to it as far as Blanquefort, via several stations including the existing SNCF stop at Bruges. This new line is expected to in service at some time during 2015.[5]

A new Line D tramway is in the planning stages.[6] This new 9.8 kilometres (6.1 mi) line will travel northwest from Bordeaux through Le Bouscat, Bruges and Eysines, ending in Le Haillan.[6] Construction on this new Line D is expected begin in 2015, and it is projected to be in service by 2017.[6]
